Hazard safety systems, which may include one or more hazard detection devices (e.g., smoke detectors, carbon monoxide detectors, motion detectors, etc.) electrically coupled to a control panel via one or more wires of a control panel system, can be used in residential, commercial, and industrial settings to detect and warn of hazardous conditions for safety considerations. Sometimes, such control panel systems may be referred to as security panel systems or central panel systems. One known control panel system may be configured to be interfaced with each hazard detection device of a hazard safety system in such a way that each hazard detection device is powered by power provided over the wires of the control panel system from the control panel, and may further be configured to be interfaced with each hazard detection device in such a way that the hazard detection device pulls more power from the control panel system when the device changes from a normal mode of operation to an alarm mode of operation in response to detecting a hazardous condition. This increase in power drawn by the hazard detection device alerts the control panel of the control panel system that a hazardous condition exists in the hazard safety system.
As hazard detection devices advance to perform features in addition to sensing for hazards (e.g., to wirelessly communicate with remote devices), additional demands for power are needed by the advanced hazard detection devices. Issues may arise in the interfacing of such advanced hazard detection devices with control panel systems such as those described above in which increased power draw serves as an alerting mechanism. In particular, issues may arise in that an increased power draw by an advanced hazard detection device may be incorrectly interpreted by the control panel as an existing hazardous condition. Other issues arise as would be apparent to a person skilled in the art in view of the instant disclosure.
